My Mom had it; complications from Type 1 diabetes. She si fine now; it only gave her problems for a year or so as I recall. Her other health issues are much worse; her MS has kicked in after being in remission for 25 years and she can hardly walk now...Morty, glaucoma need not be serious so gathering information will be a good start...good luck! Oh and they say smoking marijuana eases the pressure behind the eyes...ain't Mother Nature grand?
love,
Peg
